To all whom t may concern:

' iication.

This invention relates to a machine for connectingor assembling radiator sections, and particularly the sections of' sheet metalJ radiators. l

The object of the invention is to provide a simple and effective machine whereby any number of radiator sections may be secured together expeditiously, 'which firmly supports the sections whilebeing assembled, andwhich machine is adjustable in various waysl to accommodate sections of various sizes and shapes.

The invention comprises the construction and arrangement of parts hereinafter" described and claimed.

In the. drawings Figure 1 represents a plan view of one form ofmachine embodying the invention, the expanding devices being omitted; Fig. 2 is a' Vfront elevation thereof; Fig. 3- isan end elevation; Fig. 4 is an elevation of the upper end -portion of one of the columns or standards, and showing an expanding 'device thereon; and Fig. 5 isa sectional elevation on the line 5 5, Fig. V3.

The machine shown in the drawings comprises a base or bed plate 1 which rests on the floor or upona suitable support, and which in turn carries two columns or standards, marked respectively 2 and 3, which are hollow cast ironmembers, and each of which is provided with a level flat top 4 to receive an expanding machine 5, which assembles the radiator sections as hereinafter more fully described.

The front face ofeach of the standards 2 and 3 is provided with suitable apertures' for receiving bolts 7 for securing'thereto upper. and lower brackets 8 and 9, which The upper brackets 8 are provided with 50 Journal boxes 10 for two longitudinally extending parallel shafts 11, and the lower brackets 9 are provided with brackets 12 in which are rigidly secured studs 13. Shafts 11 are provided at each end between 55 the brackets 8 with sprocket wheels or members 14 fixed to rotate with said shafts, while leach of the studs 13 is provided with a corresponding sprocket wheel 14a loosely journaled thereon. The corresponding upper and lower sprockets are connected to rotate together by means of chains 15 passing over said sprockets, there being four such chains in all.V Each chain comprises links of the form shown inv Fig. 3, the contiguous ends of adjacent links being cut away to provide sockets or spaces 16 therebetween for receiving the edges of the radiator sections and for sup-porting said sections while being assembled and for carrying them through the machine. The chain links are of course of a length corresponding to the thickness of the radiator sections and a separate set of chains land sprockets is provided for each different thickness of section, as will be readily understood.

-The chains 15 turn in unison, but the front shaft 11 rotates in one direction and the back shaft in the other, so that the linner' strands of the chains 15 move in the same direction and, as the sprockets are of the same size, at the same rate of speed. The two longitudinal shafts are driven by means of a single transverse shaft'17, having an operating handle 17a, and journaled'in brackets 18 attached to one of the upperbrackets 8, and

.which shaft is provided with twoworms 19, provided respectively with right and left-hand threads, and which drive worm gears 20 on the two 'shafts 11.

The strands of the several chains are held rigidly during the assembling operation by backing and spacing members 21, which fill the space between the two strands of each chain, and`which comprise two plates held together by bolts 22 and at their upper ends cut away and fitting in grooves 23 in theV sprocket member,

y chines lie directly over the openings through the adjoining bosses of the radiator sections,

standards or columns 2 and 3, and the parts carried thereby, arev adjustable lengthwise on the bed or support 1. Both of the standards are shown as adjustable, although only one thereof need be adjusted. As shown, the base or support 1 is provided with ways 30 along which the columns are movable. Both of said columns may be held in any adjusted position in said ways by suitable set screws 31 threaded through the base 1 and arranged to engage the lower end of said column. Column 2 is usually fixed or clamped in one position and is not adjusted and said tool spindles are moved down except under unusual circumstances, as for wardly into -engagement with said sections `to roll the edge of the metal of one section around theedge of the other and form a beaded joint. Any suitable expanding tool or device may be used forthis step, such as the device shown in my Patent No. 1,120,100, dated Dec. 8, 1914, for expanding head.

- After the two radiator sections are secured together another section is applied to the, machine and shaft 17 is rotated to move the sections downwardly one more step, and the third section is secured to the second in the same manner before described, the opera-l tion continuing in this manner step by step until a sufficient number of sections have been secured together to form a complete radiator. The radiator is discharged from the bottom of the machine into a pit, being released from thechain step by lstep as it moves downwardly. Vhen sufficient radiator sections have been secured together to makea complete radiator the next set of sockets or spaces 16 in the four chains is skipped and the next radiator to be assembled is begun on the second set of said notches following the last one previously v used. In this manner the operation can be fairly continuous, as the radiator sections are applied at the top of the machine, are assembled in the machine while held between the several chains and are discharged at the bottom of the machine. The four chains form efficient supports for the side edges of `the radiator sections and are rigidly held against lateral displacement by the backing members 21,- so that there is no give or lost motion.

The radiator sections at their ends are guided and held in proper registering relation with each other by any suitable means,

` radiator sections of different lengths such as the rails 25, shown as channel members having their fianges turned inwardly and along the edge of which the radiator vsections ride, and which channel members are held on the ends of studs 26 adjustable in openings in the brackets 8 and 9 and held in adjusted position by set screws 27.

TQ adjust the machine for accommodating the two some special or unusual size of radiator. Column 3 is the adjustable column and is provided with suitable means for readily moving it, such as a nut 32 carried in its base and which cooperates with a threaded shaft 23 journaled in a boss 34 in the bed 1, and which can be rotated by any suitable tool applied to the non-circular end 35 there-` different lengths by merely rotating' the v shaft 33, which carries all of the mechanism at one end of the machine, including the expanding head 5, toward the otherend of the machine. i j j The machine is also arranged for accommodating radiator sections ofv different widths, and for this purpose the journal boxes 10, the brackets 18 in which the shaft 17 is journaled, and the stud supports or brackets 12 are adjustable lengthwise on the brackets 8 and 9, which arel shown as provided with T-slots 40 for receiving the headed ends of the bolts 41 for securing said members.- to the brackets. It will also be understood that the worms 19 lare splinedto shaft 17, so that they can move longitudinally thereon. The expanding machines 5 are preferably rigidly mounted upon the platforms 4 of the standards 2 and 3, 'and adjacent radiator sections are always placed -midway betweenthe side edges o`f said sections, so that to accommodate sections of different widths both of the shafts 11 and the side chains at both edges of the radiator sec- 'tion must be adjusted to accommodate sections i of* a ,different width. Consequently,

when the machineis to be adapted for a narrower section the two sets of chains are ad- .fjusted toward each other, while when a 2. A mach`ne for assembling radiator sec- 'ranged to act upon said sections between their edges for assembling the. same.
